Guhring 9037410065000 Square End Mill 0.256 in 3 Flute Carbide

Product Description

The GUHRING 9037410065000 is a solid carbide square end mill engineered for precision metal removal in demanding machining applications. Part of the Series 3741 product line, it features a 0.2559 inch diameter, a 0.512 inch length of cut, and three spiral flutes with a 45-degree helix angle. The FIREX coating provides enhanced hardness and thermal resistance for extended tool life under elevated cutting temperatures. This is a single-end, centercutting design, allowing plunge entry as well as peripheral and slot milling. It is suited for machinists and CNC operators working with tight-tolerance components.

This end mill is designed for use on CNC machining centers and manual mills where close tolerances are required. Primary workpiece materials include cast iron, stainless steel, and steel. Secondary workpiece material codes indicate suitability for non-ferrous metals and superalloys as well. The right-hand cut and right-hand flute configuration is standard for conventional spindle setups. The straight cylindrical shank at 0.2559 inches in diameter fits standard collets and end mill holders.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and stainless materials
• FIREX coating provides thermal barrier and reduces built-up edge in high-speed cutting
• 45-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Centercutting geometry allows direct plunge milling without pilot hole
• Three-flute design balances chip room and surface finish for medium-to-finish passes
• Mill diameter tolerance h10 and shank diameter tolerance h6 for consistent fit in precision toolholders

Compatibility

Designed as an OEM-style replacement or direct application tool for use with standard straight-bore collet chucks and end mill holders accepting a 0.2559 inch cylindrical shank, consistent with Series 3741 tooling specifications.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and locked out before changing tooling. The shank should be inserted to the minimum recommended grip depth for the holder being used to avoid deflection or pullout. Verify runout with a dial indicator after tightening, as excessive runout will accelerate wear on carbide tooling.
